???????? I do not understand what you are saying. Are you saying that using ethanol will absorb CO2, or that creating ethanol kills plants that utialize atm. CO2, so there is a reduced number of plants to remove CO2 from the atmosphere? Or is using ethanol benificial because the post-combustive by-products are *more* apealing to the atmospheric influx.
I wonder if you mean that ethanol *burns* cleaner. There by reducing the ppmv/gallon of gasoline introduced into the atmosphere. This then is defined as a "stablization" of the % of anthropogenic carbon dioxide input to the troposphere via auto emmisions.
Is this the right train of thought? If so wouldn't it be equally or not of greater importance to focus on Carbon Monoxide or tropo. Ozone emmision via combustive processes? Does ethanol have a reduced % of these emmisions, relative to *standard* gasoline?
